LINER FOR CENTBIFUGAL CREAM-SEPAEA'IORS.

Specification of Lettprs, Patent.

Application filed September-25, I906. Serial No. 33?,221.

To all whom it may conce n: I

Be it known that we, VV1LBUR W. MARsH and THOMAS W. ,MORGAN, citizens of the 'United States of America, and residents of Waterloo, Blackhawk county, Iowa, have in vented certain new and useful Improvements in Liners for Centrifugal CreamSeparators, of which the following is a specification.

Our invention relates to improvements in liners for centrifugal cream separators,- and the object of our improvements is to form such liner of radiating partitions curved and arranged in the separator bowl in such a manner as to promote more efficient separation of the cream from the milk, said partitions when removed from the bowl being so slidably connected as to allow them to be readily cleansed. This object we have accomplishedby the means which are hereinafter described and claimed, and which are illustrated by the following drawings, in

which Figure 1 is a horizontal section of a separator bowl, showing our improved liner in an upper plan view, Fig. 2 is a side elevation of our said liner, and Fig. 3 is a detail view, showing the manner of slidably connecting the plates of the liner so that they may be readily separated when taken out of the bowl. I

Similar reference characters refer to similar parts throughout the several views.

The said liner consists principally of a plurality of curved plates of rectangular projeotion, their curvature being alike. These plates, however, are of different widths, the plates 1), for instance, being narrower than the plates 0, the former preferably being one half the width of the latter. There are an equal number of plates of each width, and

they are arranged alternately within the separator bowl 0: as shown in Fig. 1. The plates 0, of the greater width, are provided near their inner edges with perforations h, and the plates 5, of the lesser width, are provided near their inner edges with perfora- Similar perforations i are also 9 is a split ring whose separable ends f may be passed through ,perforations h in the plates 0, and (Z is another split ring'whose separable ends'e may be passed through the perforations i in both series of plates 1) and c, the functions of said rings being to slidably connect said plates together and keep them in a certain alinement within the bowl a. The curvature of all of said plates issuch, that when introduced within the bowl they will lie therein at all points at approximately equal distances from each" other. In other words, the plates 0 are equally spaced apart, and the plates 1) are equally s aced apart, while the widths of spaces etweeii the lates b and c are always the same. esser width of the lates b, however, imparts a new function to th narrower spaces 1. The object of thus'.nar rowing the interspaces between the plates, is to interpose additional frictional surfaces near the inner periphery of the bowl. The

e liner, that of narrowing the spaces 7: by dividing them to form two larger amount-of separation of the large globules of cream from the whole milk takes place within the s aces k, but itis necessary for the proper ant efficient separation of the minute globules of cream to somewhat obstruct the movement outward of the milk under centrifu al stress and furnish additional frictional surfaces of narrower plates 1) to which such small globules may be drawnv The greater resistance and directed inward. to outward movement experienced in the spaces Z by these means thus more efiioiently strips the minute particles ofcream from the partly skimmed milk, and such cream flows toward the axis of the bowl along the surfaces of the interposed plates 1). As will be seen by referring to Fig. 3, when the liner has been removed from the bowl,

claim as new and desire to secure by Letters Patent, is

1. A liner for a centrifugal cream separator, composed of a plurality of vertical plates spaced apart and intersecting both the neutral and skimmed milk zones of the bowl, and a plurality of narrower vertical plates intersecting the skimmed milk zone of the bowl, each narrower plate being located be tween two of the broader plates and spacedapart therefrom on each side.
